Switching ratings by voltage
The 3RH2911-1HA11-ZW98: The auxiliary contacts carry a maximum of 10 A. Rated operational current varies by voltage: 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 6 A at 250 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. For AC-15 duty at 690 V the rating is 1 A. The AC-15 rated operational current values at 24 V (10 A), 60 V (4.7 A), 110 V (3 A), 220 V (1.2 A), 440 V (0.5 A), and 600 V (0.26 A) define the inductive load switching capability for control circuits.
